In the past I've heard that MS-DOS 3.1 and PC-DOS 3.1 are not the same. My own efforts to get the cluster size on my 20 MByte dribve under MS-DOS (on a Xerox 6064) to be 2K rather than 8K seem to confirm this. It seems that MS-DOS 3.1 cannot handle a 16 bit FAT entry. In general, be very cautious about assuming that *anything* under PC-DOS is the same as under MS-DOS. It would also be nice if people specified which DOS they were using, instead of just saying "DOS". /Don -- Everybody wants a happy ending. arpa: Wegeng.Henr@Xerox.COM uucp: ihnp4!rocksvax!dw
